玉米在农业生产中占有很重要的地位,被誉为“高产之王”、“饲料之王”.考虑到未来的农业生产结构:畜牧业将会占有较大的比重.在我国南方水稻区,如何以农促牧,以玉米代替稻谷养猪和发展养鸡事业,关键是在年周期内单位面积的总产量超过双季稻.为了鉴定引进的玉米杂交种在湖南的适应性、丰产性,评选出适宜于湖南稻田改种的旱熟高产玉米杂交良种,从1980年起,我们先后从全国部分省市引进了29个杂交玉米组合,根据生育期长短和产量高低进行了比较试验和多因素栽培试验.现将三年(1981～1983)的试验结果报导如下.
Corn plays a very important role in agricultural production and is known as “the king of high yield” and “the king of feed.” Considering the future structure of agricultural production, the livestock husbandry will occupy a larger proportion. In the southern rice area, how to promote agriculture by grazing, replace the paddy with corn and develop chicken business, the key point is that the total output per unit area exceeds that of double-cropping rice in the annual cycle.In order to identify the adaptability of introduced hybrid corn in Hunan , High yield, selected suitable for paddy field in Hunan drought-tolerant high-yielding maize hybrids, from 1980 onwards, we have introduced from some provinces and cities nationwide 29 hybrid corn combinations, according to the length of the growth period and yield were compared Tests and Multi-Factor Cultivation Tests Three years (1981-1983) test results are reported below.
